Replying to supplementaries during the Question Hour, Minister of State for Housing and Urban Development Hardeep Singh Puri said the third phase of Delhi Metro involved construction of 190 km rail tracks

The detailed project report (DPR) for the proposed metro line from Noida Sector 62 to Vaishali via Indirapuram and Mohan Nagar is in the final stages and Delhi Metro Rail Corporation (DMRC) is expected to submit the DPR by January-end, officials said

This section will be Delhi Metro’s first ever corridor to be operated using the Communication Based Train Control (CBTC) signalling technology which will facilitate movement of trains with a frequency of 90 to 100 seconds.

The Phase-III corridors — primarily the Pink Line (Majlis Park-Shiv Vihar) and the Magenta Line (Janakpuri West-Botanical Garden) — will form “rings” around the existing corridors that are radial in nature.
